How to choose workout underwear: expert tips on fabrics and hygiene

Experts say that wearing the wrong underwear during exercise can cause irritation and contribute to conditions like thrush, but it does not directly cause UTIs. They recommend moisture-wicking fabrics and changing out of damp clothing promptly. The article advises on materials to avoid and mistakes to avoid at the gym.

The article highlights that while many people carefully select athletic tops and shoes, underwear choices often go overlooked despite the significant effects of sweat and friction during exercise. Experts note that repetitive movement combined with tight, non-breathable fabrics can irritate sensitive skin, particularly for individuals already prone to conditions like eczema or dermatitis. Moisture-wicking materials are recommended because they draw sweat away from the body, while staying in damp clothing for extended periods may create an environment where yeast overgrowth becomes more likely in susceptible individuals. The piece also clarifies that urinary tract infections stem from bacterial entry into the urinary tract rather than from sweaty underwear itself, though prompt changing of damp garments remains sensible hygiene advice, especially for those with recurrent infection histories.
